While conservatives claim these laws boost the economy, workers suffer. According to the Economic Policy Institute, these laws do not create jobs, they reduce all workers' wages by about $1,500 per year, and workers in anti-union states are less likely to receive health insurance and pensions through employers.

Local 150 president and business manager James M. Sweeney said in a statement, "This is a victory for the middle class. These laws are nothing but thinly veiled tools to weaken unions, and this is a big win for workers who rely on unions to provide decent wages and benefits."

The case may now go to the United States Supreme Court, where the anti-labor law is expected to be upheld. The Indiana constitutional clause in question has historically only applied to individuals, so the Supreme Court would have to be convinced to apply it to unions as well in order to strike it down.
